COMPOSITION, FILLED WITH POLYOLEFIN AND ACTINIDE POWDER Russian patent published in 2017 - IPC C08K3/22 C08K5/00 C08K5/01 C08K5/09 C08L23/02 G21C3/42 C08L91/02 

FIELD: chemistry.

SUBSTANCE: described the composition for nuclear fuel, filled with the actinide powder, containing the organic matrix and the actinide powder or the mixture of actinide powders, characterized in that it contains at least: the plasticiser with alkane, in which the chain of the longest radical contains at least several tens of carbon atoms, and presented in the volumetric content from 20 to 70% relative to the total volume of only organic compounds; the binder, containing at least the polyolefin polymer, which is the low density polyethylene and/or polypropylene, and it is present in the volumetric content from 20 to 50% with respect to the total volume of only organic compounds; the dispersing agent, containing the carboxylic acid or its corresponding salts and presented in the volumetric content of less than 10% with respect to the total volume of only organic compounds. The above mentioned actinide powder or the above mentioned mixture of actinide powders is from 40 to 65 volume % with respect to the volume of the filled matrix.

EFFECT: produced composition, containing the actinide powder, which makes it possible to perform the powders injection moulding.
